Nanex is the creator and developer of NxCore, a streaming whole market datafeed
with an easy to use API. Nanex supports NxCore and develops applications that
run on the NxCore platform.
NxCore (pronounced n'core) is a high-performance, real-time streaming datafeed
(ticker plant) that brings the whole market to your workstation or desktop
computer. NxCore excels in delivering and databasing all the quotes and trades
transmitted by the exchanges, even in the hyper-active U.S. Option market
(OPRA) which now transmits over 1,700,000 quotes per second, and 6 billion
quotes per trading day.

NxCore has
an easy to use API for developing trading software. No parsing required, it
uses simple fixed structures and includes important and frequently used
information in every quote and trade update. NxCore includes tools to help you
visualize and understand data relationships in the feed. And NxCore lets you
replay the data at blazing speeds (2 million+ updates/second) on inexpensive
hardware. Converting from existing feeds becomes a trivial exercise.
NxCore databases everything; all quotes, trades and
other real-time updates are stored on your computer. If you are developing or
have your own in-house ticker plant, NxCore is ideal for evaluating your
ticker's output performance and data integrity. NxCore also makes an ideal
back-up feed, ready to go online should your primary feed fail or require
down-time. |
NxCore requires minimal resources .
Unlike some datafeeds that require hardware costing over $10,000, NxCore can
run on a low-end Pentium laptop (1.0 GHz, 256MB of RAM, 80GB IDE hard drive)
and receive and database 1,400,000 quotes/second, over 6 billion/day; and CPU
usage will remain under 5%
NxCore is extremely efficient in bandwidth
utilization and will save you thousands of dollars in monthly communications
costs. In a single T-1 (1.5mbps), it will fit 40,000 quote and trade updates
per second; In 6.0 mbps, it will fit 160,000 updates/sec. Other OPRA feed
providers now require a T-3 (30 T-1 lines) and yet provide less information per
update than NxCore. Plus, NxCore offers an optional BBO only stream for OPRA
data that is 40% smaller than the full OPRA stream. |

Nanex currently offers historical market
data from January 2004 to the present day. The data is in the NxCore tape
file format. There are three major benefits for doing it this way. It's in the
exact same format as the data during real time. All the data
is synchronized, unlike other data services that provide data
by symbol and then one has to synch all symbols and guess which quote came
before the trade. It's compressed over 90%, saving hard drive
space and time. Nanex has the ability to create tapes with only information
that is necessary. Tapes can be trades only from one exchange or all exchanges
that we offer. Checkout the historical page for more details! |
